Patented June 24, 1930 UNITED STATES GEORGE IEECK CAULKINS, OEDETROIT, MICHIGAN CABLE-FASTENING nnvrcn Application filed April 26,

This invention relates to improvements in cable fasteners, and refers moreparticularly to fasteners by which two portions of a cable may be securely held relativeto one another. t

It is an object of the invention to provide a cable fastener by which two portions of a cable may be secured relative to one another after a section of the cable intermediate the two portions has been passed around a fixed member such as a pole, and to so construct the fastener that it may readily be. placed in position and tightened .by anyone working 011 a pole or other elevation. Another object of the invention is to provide such a cable fastener which may be utilized to hold two portions of each of more than one cable, and by which all the cable portions are held by common tightening means which cooperate with the fastener.

, With these and other objects and advantages in view, which will become ap-v parent as the specification proceeds, the in vention is hereinafter more fully described with the aid of the accompanying drawings, in which: Y

Figure 1 illustrates a-perspective view of the invention holding two portions of a cable and with a section of the cable intermediate the twoportions around a pole.

Figure 2 shows a side invention.

Figure 3 is a plan view of the fastener in open position. i Figure 4 shows a modified construction, and I Figure 5 is a view of one half of the fastener shown in Figure 4 with the serrations or corrugations arranged transversely.

Figure G is a reduced sized viewof a further modification in construction.

Referring tothe drawings, more particularly to Figures 1, 2 and 3 thereof, 1 desiga nates a pole around which a cable 2 is;

passed, and 3 indicates a fastener which con sists of two portions?) and 3 s In the usual form of construction these .two portions 3 and 3 are pivotally. connected by a hinge pin 4:, and have, towardstheir other extremities, openings 5 therethrough sub-c elevation of the 1929:. Serial No. 358,309.

stantiallyat right angles to theaxis of the pin 4. "One of the sections 3 is also'usually provided with a recess 7 on its outer side to'receive the head of a bolt 6 and hold the r latter against rotation when the nut 6 is being-tightened. V V

Transversely of the adjacent sides of the fastener portions-3 and 3* Opposed substantially semi-circular recesses 8 and 8 respectively are provided. In these recesses serrations or corrugations 9 and 9? are formed which are I generally spirally directed to conform to the normal. spiral winding of a cable as indicated at Figure 8, though, when desired, these serrations or corrugations may be otherwise directed.

'When the fastenerportion 3 is moved .into open position as indicated in Figures 2 and 3, portions of the cable 2 are placed in therecesses 8 of the fastener portion'3", and then the fastener 'portion3 is moved into closed position so that the recesses 8 overlie the recesses 8. The bolt 6 is placed through the openings 5 and the nut 6 tightened. When this is done the serrations or corrugations 9 and 9a engage the cable 2,

take intothe periphery of the latter, and.

hold it positively against independent movement. It can be clearly seen that this simple operation can be readily-accomplished by oneman.

' In the construction shown in Figures 4 and 5, the fastener portions 3= and 3 are pro- V vided at both endsjwithboltholes 10 for the passage of boltsll by which they are held together Moreover, in this instance "the fastener portions are each -provided with four transverse substantially semi-circular recesses-2 8% and 8 so thatftwo;portions of each oftwo cables; 2 andQ", maybe held thereby. In thisinstance-it is usual toree move one of the bolts 11 and loosen the, other sufiiciently for the upper fastener porcioiifi to; be turned relative, to. the other fastener portionB' so that the portions ofthe cables 2 and 2" may be placed "in. their respective recesses 8 in the fastener portion 3. The

other fastener portion 3 'is then turned so that the second bolt 11 may be. passed through both fastenei-"portions, thenuts 11' are then tightened on the bolts and the cable portions are positively held relative to one portions are firmly held. In some cases it is preferable to utilize transverse corrugations or serrations as shown at 9 in Figure 5, though obviously they may be directed to suit the form of cable to be held. 7

Figure 6 shows a further modification wherein the fastener portions 3 and 3 are provided with openings 10 towards their extremities for the passage of bolts 11, and intermediate apertures 10 for the passage of a bolt 11 between the pairs of recesses 18 and 18 and the pairs of recesses 19 and 19. Then larger cables are to be supported this form of construction may advantageously be employed.

lVhile inthe foregoing the preferred embodiments of the invention have been described and shown, it is understood that these constructions are susceptible to such. further alterations and modifications as fall within the scope of the appended claims.

hat I claim as my invention and desire to secure by Letters Patent is; r

1. A cable fastener consisting of two fastener portions pivotally connected to one another, a plurality of recesses formed in the adjacent sides of each of said fastener portions, means for holding said fastener portions together towards their extremities remote from their pivotal connection, and said recesses having serrations or corrugations therein adapted to engage the peripheries of cables which extend tberethrougl'i, said serrated or corrugated recesses being adapted to grip two portions of each of at least one cable and hold said portions relative to one another.

2. A cable fastener consisting of two fastener portions pivotally connected to one another, a plurality of recesses formed in the adjacent sides of said fastener portions substantially parallel with their pivotal axis, said portions having openings therethrough substantially at right angles to their pivotal axis, and fastening means taking through said openings, said. recesses being adapted to engage two portions of at least one cable and hold said portions relative to one another. V 1 g 3. A cable fastener consistingof two fastener portions pivotally connected to one another, a plurality of recesses formed in the adjacent sides ofsaid fastener portions sub stantially parallel with their pivotal axis, said portions having openings therethrough substantially at right angles to their pivotal axis and towards their extremities remote from said pivotal axis, fastening means taking through said openings, said recesses having serrations or corrugations formed therein so directed as to conform to the winding of cable portions adapted to be placed in said recesses, so that the peripheries of two cable another when said fastener portions are held together by their fastenmg means.
